- Physical state: Liquid

Reference
No information on atmospheric pressure is provided; however, it is presumed that it corresponded to a standard pressure of 1013 hPa.
Based on expert judgement, it is unlikely that the boiling point of the test substance as such is 115 °C. As the test material included a portion of water, the formation of bubbles that are detected visually are likely from the water content. A boiling point of 115 °C is also not in line with the boiling point results of the two main constituents TEA (CAS 102-71-6), which has a boiling point of 336.1 °C and citrate (CAS 77-92-9), which decomposes before boiling. It is therefore expected that the test substance decomposes before boiling.
Description of key information
The boiling point was determined to be 115°C at 1013 hPa in a test performed according to EU method A.2.

As the test material included a portion of water, the formation of bubbles that are detected visually are likely from the water content.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
